Introductory inquiry activity; students choose relevant facts to describe the lifestyle of one species
In lab groups of 4-5, each student chooses a different bird
Materials: each group will need a computer with internet access
Day 1 of 4 inquiry activity; students design a simulation that produces random mating and allele inheritance in a given population of birds
Materials: randomness generators (dice, coins, cards) and art supplies
Guide students to record genotypes every generation, play 5 generations
Students finish Explaining ‘Amakihi Evolution lab by comparing work. Task each group to draw a cartoon explaining how ‘Amakihi evolved to tolerate malaria.
Students work in lab groups on Population Genetics Review worksheet.
Divide the paper into sections, each lab group translates one section into regular language. Students read translations aloud. Then watch Survivors in Paradise 2
Nontechnical Summary and Abstract
Introduction
Methods: Sample Collection
Discussion (first half - hypotheses)
Discussion (second half - results)
Conclusion
Teacher summary: Scientists were looking for differences between malaria susceptible birds from high elevation and malaria tolerant birds from low elevation. There were 3 hypotheses.
tolerant birds had better swelling response to mosquito bites
tolerant birds had more natural antibodies (NAb) in their blood
tolerant birds had a better diet with more antioxidants to fight infection
Results showed that tolerant birds had more NAb than susceptible birds. Tolerant bird blood had enough NAb to lyse foreign cells (they used rabbit erythrocytes) at 1:8 dilution whereas susceptible birds had fewer NAb and could not ever lyse foreign cells.
